The interactive map lets you geographically explore the history and science of dinosaur footprints and geology of the Connecticut River Valley. The map has four primary layers which you can look at individually, or stack them so you can see, for example, how the town of Amherst relates geographically to Lake Hitchcock

Show Maps

Check-boxes to the left of the map let you choose what map layers to see, one at a time or stacked one on top of the other to show historical and geological relationships. The map layers are Present-day Roads & Towns, Hitchcock's 1857 Ichnological Map, which shows where he found "fossil bird" (a.k.a. dinosaur) footprints, Hitchcock's 1834 Geological Map, and Lake & Glacier, which shows the last glacier to cover this region and the lake that formed as the glacier melted, Lake Hitchcock. (Lake Hitchcock drained out thousands of years ago, so don't expect to swim there!)

Markers

There are three categories of map markers: Fossils & Geology, Places to Visit, and Historical Sites. Selecting a category will plot the relevant markers on the map. Fossils & Geology has outdoor sites and museums with rocks and fossils. Places to Visit includes museums, parks, and indoor or outdoor entertainment venues relevant to the historical stories told on this website. Historical Sites show where some of the events in the stories took place. Some of these are "drive-bys" on private property, such as the house in which the Hitchcocks lived in Amherst. Others, such as old quarries, can be visited.

How to Use the Map

Show Markers

There are three categories of map markers: "Fossils & Geology" sites, "Places to Visit" and "Historical Sites". Selecting one of these radio buttons will plot the relevant markers on the map.

Links to Markers

You can find more information about a site in two ways. Clicking a marker on the map opens a window with information for that site. Clicking a site in the Links to Markers box to the right of the map will center the map on the chosen marker and open that same window.
